⸻ Timber Aluminium Windows

HF 520

The HF 520 timber-aluminium windows showcase a sleek, modern design with a flush finish. Unlike traditional window systems where the glass unit is housed within a visible sash frame, the innovative glass sash of the HF 520 makes the frame invisible from the exterior, creating a seamless look that resembles fixed glazing. Its slim profile maximises the amount of natural light that pours into your home.
